Abstract: 743,512. Treating waste effluents. FROMAGERIES BEL. Sept. 22, 1953, No. 26083/53. Class 111. Waste water from, e.g., milk industries, is subjected to a first (optional) separation of the heavier solids in suspension, then to a first aeration in a closed circuit; a flocculating agent is added towards the end of this first aeration step, the waste water is allowed to stand to permit flocculation and clarification to take place, it is then subjected to a second closed circuit aeration and finally subjected to a final separation. Water from a sewer 1 is received in a suction sump 2 whence it is pumped by a pump 3 to a centrifugal separator 9 after which it passes along a conduit 4 to a tank 6. When full, the tank contents are withdrawn by a pump 11 and passed through an aerator 13 supplied with compressed air at 24 before return to the tank. This circulation may continue for about two hours, and towards the end of it flocculating agents, e.g. ferric chloride and slaked lime, may be added. After about a quarter of an hour the circulation is stopped and the liquid allowed to stand for an hour. Circulation is then resumed for a period of not less than four (preferably from six to twelve) hours. The water is then withdrawn along a conduit 17 by a pump 29 and passed for final separation to the centrifugal separator 9, whence purified effluent passes along a conduit 20 to a sewer 21. Preliminary aeration may be effected by perforate pipes immersed in the sump 2. At least one other tank 6 is arranged in parallel with that shown, conduits, pump and aerators being suitably duplicated, for alternate working. Effluent from the separator 9 may be returned to the sump 2 along a conduit 28 for further treatment in the case of insufficient purification, or it may be returned to the tank 6. A conduit 35 is provided for by-passing the centrifugal separator if desired, and a conduit 36 is provided to allow some of the residuary water to be run into the sump 2.

Title: Improvements in or relating to liquid pumping systems
IPC: F04B23/04
Filed: 1939-09-25
Abstract: 535,936. Pumps ; hydraulic control systems. AUTOMOTIVE PRODUCTS CO., Ltd., and PARKER, S. M. Sept. 25, 1939, No. 26609. [Class 102(i)] [Also in Group XXIX] A liquid pumping system especially adapted for operating remote-control systems on aircraft is constructed so as to safeguard the supply of liquid in the event of a leakage in the pump or connections. As applied to a system in which one main reservoir 37 supplies two or more pumps 12, 13, driven by separate engines the supply of liquid from the reservoir 37 to each pump is controlled by a mushroom-valve 26 which is acted upon by a spring tending to close the valve, and each valve is opened by the pressure of liquid delivered by the pressure pipe 18 of each pump acting upon the end 33 of a piston rod 27 attached to the valve 26. When the rod 27 is raised to open the valve 26 a port 20 is opened by the motion of the rod 27 and the pressure liquid can pass via pipe 21, 22 to the control system, and a pipe 23 returns the liquid to the reservoir 37. The inlet pipe 17 of each pump is supplied from an auxiliary reservoir 10 or 11 which receives its supply from the reservoir 37 when the valve 26 is open via an L-shaped port 29, 31 which enters the closed reservoir below an air space 35. In a modification Fig. 3, the auxiliary reservoir is dispensed with and the port 16 is extended beyond the port 31 to which it is connected and a spring-pressed non-return vent valve 41 is fitted in the end of the pipe 16. In all cases if a leak occurs in a pump or its inlet or outlet the pressure of the liquid is insufficient to open the valve 26 of that pump, and the supply of liquid from the reservoir 37 to that pump is cut off.
